2. Flash version: uniflash_sl.4.6.0.2176.exe

3. Flash files:  mmwave_industrial_toolbox_3_2_0\labs\lab0004-high-accuracy-14xx\lab0004_high_accuracy_14xx_pjt\prebuilt_binaries

     xwr12xx_xwr14xx_radarss.bin

         xwr14xx_high_accuracy_mss.bin

4. Refer the high_accuracy_14xx_lab_user_guide.pdf user guide, and will happen the below error:
